In this regard, what is the radiation pattern of an antenna?
A radiation pattern defines the variation of the power radiated by an antenna as a function of the direction away from the antenna. This power variation as a function of the arrival angle is observed in the antenna's far field.
Considering this, what information is available from a radiation pattern?
Related to the radiation pattern of an antenna, a number of important parameters exist, such as radiated power, radiation efficiency, directivity, gain, and antenna polarization.
Directivity is expressed in dB. The higher the directivity, the more concentrated or focussed is the beam radiated by an antenna. A higher directivity also means that the beam will travel further. An antenna that radiated equally well in all directions would be omni-directional and have a directivity of 1 (0 dB).
